Much clearer now. One final part I don't understand.
<div> </div>
<div>>>> "%d is the result of %d + %d" % (6+7,6,7)</div>
<div> </div>
<div>I understand (I think) the 6+7 part but why the ,6,7 after that. I could <br>see how either '6+7' or '6,7' would be the correct format but not both.</div>

The second gets 6 <br>the third 7...<br><br>Look at the first example in the loops topic in my tutorial.<br>It uses variables in the same way rather than literal values, <br>that might make it more obvious. Maybe :-)<br> </div></div></div>HTH,<br><br>Alan G.<br><br></div></body></html>
